SKRIPSI PENGARUH MACAM ZAT PERANGSANG DAN JARAK TANAM TERHADAP PERTUMBUHAN DAN HASIL KEDELAI (Glycine max (L) Merril)
ABSTRACT
The experiment by the object of investigating the in- fluence of sort of stimulus substance and plant spacing to the growth and yield of soybean (Glycine max (L.) Merrill) was carried out at Village of Butuh, Sub District of Sa- wangan, District of Magelang, Province of Central Java fron 31 July 1987 until 14 November 1987. The soil type was Re- gonol, the soil pH was 6,2 the altitude of the field was 425 metre above lovel place of the sea.
The experimental design used was Randomized Complete Block Design (RCBD) was composed by Split Plot Design (SPD), consist of two treatment factors by three replica- tions. The treatment factors were examined:
1. Factors were stimulus substance (3) as main plot:
Z0 : Without of stimulus substance (control)
Z1 : Atonik 625 oc were solved in 625 1 of water per ha 22
Z2 : Vegimax 50 cc were solved in 500 1 of water per ha
2. Factors were plant spacing (J) as sub plot:
J1 : Plant spacing (20x15) om
J2 : Plant spacing (25x15) cm
J3 : Plant spacing (30x15) cm
J4 : Plant spacing (20x25) cm
The result of experiment showed that:
1. The treatment of stimulus substance non significant to the height of plant, full flowering time, number of for tile nodes, number of filled poda, number of unfilled pods, weight of dried seeds, frosh weight of plant, dry weight of plant and harvest index; but significant to the weight of 100 dried seeds.
2. The treatment of plant epacing non significant to the height of plant, number of unfilled poda, weight of 100 dried neede and harvest index; but nignificant to the full flowering time and very nignificant to the number of fertile nodes, number of filled pods, weight of dried seeds, fresh weight of plant and dry weight of plant.
3. The treatment of stimulus substance and the treatment of plant spacing non interaction to the all observation. The highest result of the weight of dried seeds per plant reached at treatment combination ZJ (Atonik 625 cc were solved in 625 1 water per ha, plant spacing 20x25 cm) even though per plot reached at treatment combination Z12 (Atonik 625 cc were solved in 625 1 water per ha, plant spacing 25x15 cm). The utilization of stimulus substance %2 (Vegimax 50 cc were solved in 500 1 water per ha) to make ascend the weight of dried seeds per plant and the utilization of stimulus sube- tance 21 (Atonik 625 cc were solved in 625 1 water per ha) to make ascend weight of plant.
